Re: Stop at Intel Management Engine BIOS after System Update 9JAN09

No solution that I know of yet. I was able to boot to the hardrive by taking out the memory and disabling the Intel AMT in the BIOS. The I pressed F8 slowly until WIndows XP came up. After that I was able to downgrade the BIOS in XP using the winflash utility that comes with the BIOS package. Why not use the Bootable CD you ask? I could not use the Bootable ISO CD because the new BIOS did not boot up to the CD as well

Well, problem solved. Or I should say half solved.

Brought my x200s to service centre in Quarry Bay, HK. The person at service desk was very helpful, telling me this is not the first case! He immediately open the RAM latch and found the source of the problem - Kingston 2G RAM, one in each ram slot. Apparantly, BIOS ver 2.02 does not like Kingston Ram. Since I don't have the origianl 1G RAM that comes with the notebook, they took out all 4G RAM, replace it with a stock RAM, boot up the x200s, and downgrade my x200s' BIOS to the previous version.

Popped both my Kingston RAM in the notebook, boot up, wola, everything works as before.

Word of advice: DON'T UPDATE TO BIOS 2.02 IF YOU ARE USING KINGSTOM RAM!

Lenovo: As a responsible company, please put a note on the release note and warn customer before hand!

It's not just Kingston RAM. I bought 2x 2GB sticks of G.Skill RAM from Newegg (link) that have the same problem. It doesn't work with one chip, two chips, or the factory 2GB and one of the G.Skill chips. Only the factory chip will allow a boot (it says "Hynix" on the factory one). I don't think it's the Intel Management BIOS that's the problem though because if you go into the BIOS and turn off the Network Boot Option ROM then it hangs at a different point (unknown, just a blinking cursor).
